To all whom it may concern:

Be it known that I, JOHN M. ROHLFING, a'citizen of the United States,residing at the city of St. Louis, State of 'Missouri, have invented acertain new and useful Improvement in Nailing-Strip Mounts forFreight-Cars, of which the following is a full, clear, and exactdescription, such as will enable others skilled inthe art to which itappertains to make and use the same, refe'rence being had to theaccompanying drawings, forming part of this specification, in which vFigure 1 is a cross sectional view through a freight car showing thearrangement of my improved nailing strip mounts; Fig.2 is an enlargedsectional view through one of the mounts; Fig. 3 is an elevational viewof one of the mounts.

This invention relates to'a new anduseful improvement in nailing stripmounts for freight cars and consists of a simple, easily applied device,a plurality of which mounts are preferably countersunk in the side wallof the car whereby. nailing strips 'of wood may be detachably secured inposition either vertically, horizontally, or at an angle -as therequirements of the particular lading being transported demand.

Heretofore, and indeed so-called automobile box carhas. been, and isusually constructed with its side walls arranged inside the postsand'diagonals constituting the side framing of the car. This is known asa sheathingless car on account of the absence of the outside sheathing.It is obvious that the lining or wall arranged inside the posts anddiagonals provides a smooth uninterrupted surface which is verydesirable in loading and unloading certain classes of freight, suchasautomobiles, etc.

It is very desirable, if not necessary, in packing freight, such asautomobiles, in a car of the character described, especially where themachine is assembled and runs, on its own wheels, to prevent allmovement of the lading incident to shocks and jars to which the car issubjected. To accomplish this, it has been the practice in some cases tonail cleats against the side walls at proper points so as to provide anailing base to which the ends of cross timbers are attached, said crosstimbers being so disposed as to prevent longitudinal shifting of theload. These cleats may also be used for at present, the

the attachment of cross timberslon which a supplemental flooring issecured whereby a greater quantity of freight may be packed:

in the car with little or no danger ofthe different pieces or assembledpartscontacting with each other possibly to the mutual injury of theirpaint, or finish. These cleats, cross timbers, and supplementahfiooringboards are provided by the shipper, and when the car reaches itsdestination, are generally removed by: the consignee with the resultthat in many 'cases the side walls of the car are puncturedby the nailsused for securing the cleats in position. These nail holes thus left inthe side wall provide ways for the ingress of water into the car to thedetriment of subsequent shipments,

and for such injuries occurring in transit,

the railroad is, of, course, responsible. Further, the repeatedinsertionand removal of nails splinters the side walls and rail, and dustaccumulating in the nail holes causes the side wall to rapidlydeteriorate.

My present invention contemplates the use of small metal sockets,preferably countersunk, in the sidewall so as to preserve the smoothinner surface thereof, said sockets being arranged at such locations asexperience dictates, They may be in two horizontal rows and extendthroughout the entire length of the car, as shownin Fig. 1-, or they maystart at a given point from each end of the car.

In the drawings, 1 indicates the side wall of the car'which at desiredpoints is recessed, preferably by an augur, to receive a metal socket 2preferably made circular inform to fit into the circular recess in theside wall and be flush with the inner face thereof. A. bolt 3 is shownfor securing the socket in position, said bolt passing through anop'eningin the back wall of the socket and side wall of the car, but itis obvious that many other formseof fasteningdevices'may be used, ifdesired, to secure the socket in place.

' 2 indicates wings extending inwardly toward each other andconstituting front 7 H y rangement for receiving the head of a bolt 4passing through a wooden cleat 5.

The head of bolt 4 is prevented from turning by engaging the lower wallof the socket, and hence the nut on the inner end of this bolt may beturned up so as to secure the cleat firmly in place. In introducing thehead of bolt into position, the same is turned so that its faces lie atangles of and when in the key hole the bolt is turned so that its facesare vertically and horizontally disposed, thereby enabling it to fitsquarely against the bottom Wall. When in this position, if a cleatshould accidentally be raised so as to locate the head of the boltopposite the enlarged portion of the key hole opening, the head of thebolt cannot pass througlnas it is necessary to turn the bolt head to itsintroducing position before it can be removed.

From the above, it will be seen that removable cleats are provided whichcan be placed in any desired position, vertically, horizontally, or atan angle, said cleats forming nailing strips for cross timbers, floorsupports, etc., and when the cleats are removed, the side walls of thecar are not injured in any way, and the smooth, unbroken surface of thewall is preserved.

What I claim is:

1. The combination with a car wall of a socket mount whose front wall isprovided with an opening, the upper portion. of which is enlarged so asto receive the head of a bolt, and a bolt whlch, when its head isintroduced into said opening, is turned 7 1 1esses,'this 19th day ofApril, 1915.

to secure proper cooperation with said socket mount.

2. The combination with a car Wall of a socket mount which is circularin shape and whose front wall is provided With a key hole openingdesigned to cooperate with a bolt head, the upper enlarged portion ofsaid opening preventing the removal of the bolt head when said bolt headoccupies its" engaging position relative to said socket mount.

3. The combination with a car Wall of a socket mount which is circularin shape and provided with a key hole opening in its front wall, meansfor securing said socket mount to said car Wall, a bolt, the

head of which is adapted to pass through the key hole opening in theWall of the socket mount, and a nailing strip supported by said bolt.

4. The combination with a car wall of a nailing strip mount comprising asubstantially hollow member seated in said Wall, means for securing saidmember to said Wall and a nailing strip engaging bolt having its headremovably seated in said hollow member. 1

5. The combination with a car wall, of a cup-shaped socket counter-sunkin said wall, means for rigidly fixing said socket to said wall, lugsintegral with the front of said socket, which lugs are spaced apart andarranged to form an irregular opening, and a nailing strip supportingbolt, the head of. which is adapted to pass through said irregularopening and engage behind the lugs on the socket.

In testimony whereof I hereunto afiix my signature in the presence oftWo wit- JOHN M. ROHLFING.
